Why Parexa

Everything you need to make software speak.

One API, one key, one bill. No voice-clone upsells, no seat pricing, no feature you have to negotiate for.

322 voices, 75 languages

Every major accent, from en-US Aria to ja-JP Nanami. Native pronunciation, not transliteration.

From $0.0025 / 1k chars

Up to 32× cheaper than ElevenLabs and 40× cheaper than MiniMax. No seats, no watermarks, no surprise fees.

Drop-in API

Two POST requests and you are live. Bearer auth, JSON in, audio out — or multipart audio in, text out.

Speech to text included

Transcribe uploads up to 25MB in 100+ languages with the same key, on every paid plan.

Built for global products

Switch accent per request. Same sentence, 75 locales — one voice layer for your entire app.

Clean audio, commercial use

No watermark, no attribution requirement, no per-platform licensing games. Ship it.

The API

One request. Natural audio.

Bearer auth, JSON in, audio bytes out. Change the voice name to change the accent — same request, 75 locales. Transcription and voice listing use the same key.
